17-meter Wire Beam DX Antenna

Want to “DX” on 17–meters?  Ok, so you don't have a linear amp or tower-mounted rotatable beam antenna.  You can still rack up those DX QSLs by building yourself an inexpensive 2–element wire beam antenna that performs well at a height of 20'.  All you need is some #14 AWG wire, insulators, 2” X 2” X 8' treated furring strips, and miscellaneous parts & fasteners.  The antenna  is based on the design created by Les Moxon (G6XN, SK).  The furring strips can be used to build a rectangular frame for the antenna.  The completed antenna will be a little over 20' long and 3' wide. By building a mounting system that enables the mast to be manually rotated, you have an inexpensive rotatable beam antenna with excellent gain and directionality.

A free program to compute Moxon antenna dimensions is available at the link below. The program has an option to generate EZNEC model files.


An EZNEC model for the 17–meter antenna is available at the link below.

Tip:  Use the online calculator at the link below to compute the distance and true bearing between your QTH and another QTH.  Street address or coordinates can be entered.  You can use the true bearing to point your new beam antenna for the best signal.

QRZ.com also provides the distance and bearing from your QTH to another QTH based on call signs.  The distance and bearing can be found by clicking the detail tab.
